26. Structure and Dynamics of Pairing Field in Inhomogeneous Fermi Superfluids

Bugra Tuzemen (IFPAN)

Talk

Spin imbalance in ultracold Fermi gases gives rise to a rich variety of structures rooted in the competition between pairing and polarization. I will present a survey of our recent results, starting from the static phase diagram where disordered configurations compete energetically with Larkin-Ovchinnikov-Fulde-Ferrell (LOFF)-type ordered states across a wide range of polarizations. I will...

56. Kelvin-Helmholtz Instability in Fermionic Superfluids: Numerical Approach

Talk

The Kelvin–Helmholtz instability (KHI) in superfluid systems with annular geometry has recently attracted significant attention. While numerical studies based on Gross–Pitaevskii and Zaremba–Nikuni–Griffin models have explained some of its dynamics, the inconsistency persists, as evidenced by incorrect predictions of the instability's growth rates. We employ the SLDA framework to simulate KHI...

38. Vortex-nucleus interaction in the inner crust of neutron star

Talk

Astronomical observations of neutron stars provide information on kilometer scales, while the nuclear interactions that govern their properties operate on femtometer scales. Describing physical processes across such vastly different length scales requires effective theoretical models. The inner crust of a neutron star is a particularly complex system, where a lattice of nuclei strongly...
